Answer:
[tex]a_{n}[/tex] = 5n
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 10 - 5 = 15 - 10 = 20 - 15 = 25 - 20 = 30 - 25 = 5
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 5 , then
[tex]a_{n}[/tex] = 5 + 5(n - 1) = 5 + 5n - 5 = 5n

Evaluate 13 - 0.75w+8x when w=12 and x= 1 over 2
Answer:
8
Step-by-step explanation:
Given:
13 - 0.75w + 8x
where,
w = 12
x = 1/2
13 - 0.75w + 8x
Substitute the value of w and x into the equation
= 13 - 0.75(12) + 8(1/2)
= 13 - 9 + 8/2
= 13 - 9 + 4
= 8
Therefore,
13 - 0.75w + 8x = 8
2 1 -5 4 3 2 -11 2 4 5 X -2 ب ا -5 a Write down the gradient of the graph.
Answer:
Gradient = -3
Step-by-step explanation:
The gradient of the graph = change in y/change in x
Change in y = the vertical distance = 3 units
Change in x = the run/horizontal distance = 1 unit
The line slopes downward, so it's a negative gradient.
Thus:
Gradient = 3/1 = -3
In ΔLMN, MN = 15, NL = 20, and LM = 6. Which list has the angles of ΔLMN in order from smallest to largest?
Answer:
m<N, m<L, m<M
Step-by-step explanation:
The angle that sees the longest side length has the bigger angle measurement
so the angles would be listed as following :
from smallest to largest :
m<N, m<L, m<M
On a map of a town a school is located (-6, 3) and a movie theater is located (-6, -15) what is the distance from the school to the theater
Answer:The distance from the school to the theater = 18 units
Step-by-step explanation:
Distance between (a,b) and (c,d) = [tex]\sqrt{(d-b)^2+(c-a)^2}[/tex] units.
Given: On a map of a town a school is located (-6, 3) and a movie theater is located (-6, -15).
So, distance between (-6, 3) and(-6, -15) = [tex]\sqrt{(-6-(-6))^2+(-15-3)^2}[/tex]
[tex]=\sqrt{0^2+(-18)^2}\\\\=\sqrt{18^2}\\\\=18\ units[/tex]
Hence, the distance from the school to the theater = 18 units
A system of equations has 1 solution. If 4x – y = 5 is one of the equations, which could be the other equation?
A- y = –4x + 5
B- y = 4x – 5
C- 2y = 8x – 10
D- –2y = –8x – 10
Answer:
D: 2y = 8x - 10
Step-by-step explanation:
A: y = 4x + 5. This has a slope of -4 Yes it could work.
B: y = 4x - 5. No It does not work
C: 2y = 8x - 10. The slope is 8/2 = 4. So No it could not work.
D: -2y = 8x - 10. The slope is 8/-2 = -4. Yes This Does work! :)
Select the correct answer.
For which system of inequalities is (3,-7) a solution?
A.

C.
x + y < -4
3x + 2y ≤ -5
D.
x + y ≤ -4
3x + 2y ≤ -5
Answer:

Step-by-step explanation:
[tex]\frac{-4}{3} * y = \frac{-3}{4}[/tex]
shift -4/3 to the right hand side . when it shifts to other side miltiplication changes to division
y = [tex]\frac{-3}{4} /\frac{-4}{3}[/tex]
now do reciprocal
y = [tex]\frac{-3}{4} *\frac{3}{-4}[/tex]
y = [tex]\frac{-9}{-16}[/tex]
minus and minus gets cancel
y = [tex]\frac{9}{16}[/tex]
y = [tex]\frac{(3)^2}{(4)^2}[/tex]
y = [tex](\frac{3}{4})^2[/tex]

Find the average rate of change of h(x) = 2x² – 7x from x=2 to x=5.
Simplify your answer as much as possible.
Answer:
The average rate of change of h(x) in the given interval is 7.
Step-by-step explanation:
When we want to find the average rate of change of a function f(x), in an interval a < x < b, we just need to calculate:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
Here we have:
h(x) = 2*x^2 - 7*x
And we want to find the average rate of change between x = 2 and x = 5
This will be:
[tex]r = \frac{h(5) - h(2)}{5 - 2} = \frac{(2*5^2 - 7*5) - ( 2*2^2 - 7*2)}{3} = \frac{15 - (-6)}{3} = \frac{21}{3} = 7[/tex]
The average rate of change of h(x) in the given interval is 7.

Q.No.1: A subset of {1,7,8 } is:
Step-by-step explanation:
you only need to provide an example ?
if your question here is complete, then the full set is
{1,7,8}
and these are all possible subsets (pick any one you like) :
{1}, {7}, {8}, {1,7}, {1,8}, {7,8}
and formally also
{}, {1,7,8}
the empty set is a subset of every set, and the whole set itself is also formally a subset.

The 2 option :)
Step-by-step explanation:
The Chords : QL ,SM , Secant : NR , Tangents : a and b , Diameter : QL, ,radii: PT , QT and TL therefore the Option A is the correct answer.
What is a Circle ?A circle is a round shaped figure , whose all points are in the same plane and at same distance from a single point known as center.
A secant is a segment that passes through 2 points on a circle, It is an infinite extension of a chord.
A tangent touches a circle at exactly one point and never enters the interior of the circle.
A chord is a line segment which connects two point on the circle.
A diameter is a chord that passes through the center of the circleThe radius is half of the diameter of the circle

Answer: 103 degrees
Step-by-step explanation: all angle of a regular triangle always add up to 180. so 62+15=77. and 180 - 77= 103
Answer:
A. 103 degrees
Step-by-step explanation:
In a triangle, the sum of angle measures is equal to 180 degrees, so by adding 62 & 15, & subtracting it from 180 you get the third angle measure of 103.
